Are seminal vesicles a potential pitfall during pelvic exploration using point-of-care ultrasound (POCUS)?

ABSTRACT:

Background

Trauma is a major cause of death among the working population. Many countries have now adopted a structured approach to trauma management in which ultrasound is used as a primary evaluation tool. While its use has direct therapeutic benefits, many artifacts and pitfalls are inherent to the technique. Knowledge of the most frequently encountered pitfalls in practice could thus help reduce the risk of error and lead to more accurate trauma assessments.

Objective

This study evaluates a potential pitfall caused by seminal vesicles during focused assessment with sonography for trauma examinations of the male pelvis performed by an emergency physician with experience in point-of-care ultrasound.

Methods

We took five static and five dynamic (3-s loops) transverse ultrasound images of the pelvis in five healthy males. The images and videos were then incorporated into an online survey and emailed through the World Interactive Network Focused On Critical UltraSound (WINFOCUS) in France and the Ultrasound and Emergency Medicine (UEM) Organization in Belgium. A questionnaire asked anonymous participants to assess the presence of free fluid in the static and dynamic images and to share information about their training and experience in point-of-care ultrasound. To validate the static and dynamic images, the survey was sent to three external radiologists for independent verification.

Results

A total of 191 individuals responded fully or partially to the survey, 114 of whom completed it. Among the 114 participants who completed the survey, the misinterpretation rate was 0.55 (95CI 0.51-0.60) for all static and dynamic ultrasound transverse pelvic views. The misinterpretation rate was 0.61 (95CI 0.55-0.66) and 0.50 (95CI 0.45-0.55) for static and dynamic ultrasound transverse pelvic views, respectively. The three external radiologists answered the questionnaire correctly without misinterpreting the survey ultrasound views.

Conclusions

Seminal vesicles are a potential pitfall when interpreting transverse ultrasound images of the male pelvis in the context of point-of-care ultrasound.

Project description:BackgroundPoint-of-care ultrasound (POCUS) is increasingly used as a non-invasive vascular access assessment method by clinicians from multiple disciplines worldwide, prior and during vascular access cannulations. While POCUS is a relatively new method to establish a vascular access in patients with complex vascular conditions, it is also essential to train and educate individuals who are novices in the techniques of cannulation so that they become proficient in performing this task subsequently on patients safely and successfully. A simulated environment may be a helpful tool to help healthcare providers establish skills in using POCUS safely and may also help them to successfully establish vascular access in patients. With this project, we sought to determine if participants of a simulated POCUS workshop for vascular access can use this technique successfully in their individual clinical environment after their attendance of a half-day workshop.MethodsA mixed-methods longitudinal study design was chosen to evaluate a point-of-care ultrasound workshop for peripheral intravenous cannula insertion. The workshops used simulation models for cannulation in combination with multiple ultrasound devices from various manufacturers to expose participants to a broader variety of POCUS devices as they may also vary in different clinical areas. Participants self-assessed their cannulation skills using questionnaires on a 10-point rating scale prior to and directly after the workshop.ResultsA total of 85 Individuals participated in eleven half-day workshops through 2021 and 2022. Workshop participants claimed that attending the workshop had significantly enhanced their clinical skill of using ultrasound for the purpose of cannulating a venous vessel. The level of confidence in using this technique had increased in all participants directly after conclusion of the workshop.ConclusionsGlobally, clinicians are increasingly using POCUS to establish vascular access in patients, and it is necessary that they receive sufficient and adequately structured and formal training to successfully apply this technique in their clinical practice. Offering a workshop which uses simulation models in combination with various POCUS devices to demonstrate this technique in a hands-on approach has proven to be useful to establish this newly learned skill in clinicians.

Project description:IntroductionPoint-of-care ultrasound (POCUS) use is increasing in pediatric clinical settings. However, gastric POCUS is rarely used, despite its potential value in optimizing the diagnosis and management in several clinical scenarios (i.e., assessing gastric emptying and gastric volume/content, gastric foreign bodies, confirming nasogastric tube placement, and hypertrophic pyloric stenosis). This review aimed to assess how gastric POCUS may be used in acute and critically ill children.Materials and methodsAn international expert group was established, composed of pediatricians, pediatric intensivists, anesthesiologists, radiologists, nurses, and a methodologist. A scoping review was conducted with an aim to describe the use of gastric POCUS in pediatrics in acute and critical care settings. A literature search was conducted in three databases, to identify studies published between 1998 and 2022. Abstracts and relevant full texts were screened for eligibility, and data were extracted, according to the JBI methodology (Johanna Briggs Institute).ResultsA total of 70 studies were included. Most studies (n = 47; 67%) were conducted to assess gastric emptying and gastric volume/contents. The studies assessed gastric volume, the impact of different feed types (breast milk, fortifiers, and thickeners) and feed administration modes on gastric emptying, and gastric volume/content prior to sedation or anesthesia or during surgery. Other studies described the use of gastric POCUS in foreign body ingestion (n = 6), nasogastric tube placement (n = 5), hypertrophic pyloric stenosis (n = 8), and gastric insufflation during mechanical ventilatory support (n = 4). POCUS was performed by neonatologists, anesthesiologists, emergency department physicians, and surgeons. Their learning curve was rapid, and the accuracy was high when compared to that of the ultrasound performed by radiologists (RADUS) or other gold standards (e.g., endoscopy, radiography, and MRI). No study conducted in critically ill children was found apart from that in neonatal intensive care in preterms.DiscussionGastric POCUS appears useful and reliable in a variety of pediatric clinical settings. It may help optimize induction in emergency sedation/anesthesia, diagnose foreign bodies and hypertrophic pyloric stenosis, and assist in confirming nasogastric tube placement, avoiding delays in obtaining confirmatory examinations (RADUS, x-rays, etc.) and reducing radiation exposure. It may be useful in pediatric intensive care but requires further investigation.
